VBA Copying Rows Into Another Workbook

I have a workbook into which a number of rows will be imported (a variable number). These will be edited then I want all the rows to be stored in a ever growing database. At the moment I simply copy these rows open a second workbook and paste the rows into the first blank row in the second sheet.

Is there a way to do this automatically.
1) select and copy all rows containing data
2) open second workbook & find first blank row
3) Paste data into second workbook
4) Save and close second workbook

I think with some effort I could manage the copying and pasting but I have no idea how to open and close the second sheet automatically.
